Usually when something drops, there's little you can do other than bring it for repairs or toss it out. I don't know what magical incantation you were expecting to get it to work again, but if you can find a time machine and go back during the mythological age it's worth a shot. Also don't ever lazily leave any machine on an unsteady surface for fear of it dropping and becoming a large paper weight. Hope you learned your lesson.Usually when something drops, there's little you can do other than bring it for repairs or toss it out.

Those circles are there as a sign that the unit has not finished loading the indicator - it's a wait signal. This happens because the processor no longer recognizes the indicator for the shows you recorded so yes, this is a big defect.
The unit is repairable - you will have to replace the hard drive and reprogram the unit - but this is a long and costly procedure. It will be cheaper just to buy a new one.

Hi Saturn et al,I had similar issues with my Pioneer DVR-520H. It completely went off for quite a while when it should be going to standby after a timer session. At the start it would come good after a few days. Eventually it went off altogether and nothing would bring it back.With my father-in-law being an electronics person we investigated with the help of the service manual which I found on the net. The finger was duly pointed at the power IC (MR2920) on the power supply board (Pioneer will sell only the complete board). I ordered the IC from the UK (nikko-electronics.co.uk) GBP8.99 which was the only place I could find it online and soldered it in myself (easy, if you can solder).All fixed and working again.Hope this helps.
